Rubber vulcanization accelerator. Rubber vulcanization accelerator pz (zinc dimethyldithiocarbamate) is a chemical substance, white powder, insoluble in water, moderately toxic. Super accelerator for natural rubber, synthetic rubber and accelerator for latex. It is especially suitable for butyl rubber that requires compression deformation and nitrile rubber that requires excellent aging resistance. It is also suitable for EPDM rubber. ?
The vulcanization temperature is 100°C, but the activity is stronger at low temperatures and has a greater tendency to scorch, which can easily cause early vulcanization during mixing. Since the products are non-toxic, odorless, non-polluting and non-discolored, they are suitable for tapes, food and medical rubber products. In the United States, PZ is approved by the Food and Drug Administration (FDA). The effect is remarkable in products such as EPDM rubber and butyl rubber.
Extended information
Accelerator for natural rubber and synthetic rubber. It has a wide vulcanization range and can be used alone or in combination with dithiocarbamates, thiurams, Guanidines are used together with other alkaline accelerators. Mainly used in the manufacture of tires, tapes, rubber shoes and other industrial rubber products.
Substances that can lower the vulcanization temperature or shorten the vulcanization time after adding rubber compounds are called vulcanization accelerators. The accelerator added to the rubber can activate the vulcanizing agent, thereby accelerating the cross-linking reaction between the vulcanizing agent and the rubber molecules, achieving the practical effects of shortening the vulcanization time, lowering the vulcanization temperature, increasing output, and reducing production costs.
